SPECIFICATION forming part of Letters Patent No. 293,788, dated February19, 1884.

Application filed October 21, 1881. (No model.)

To all whom it mag concern.-

Be it knownthatwe, FREDERICK G. SARGENT and ALLAN O. SARGENT, ofGraniteville, coun ty of Middle'sex, and State of Massachusetts, haveinvented a new and useful Machine for Cleaning Wool, of which thefollowing is a specification.

Our invention relates to machines used to separate dirt from W001without washing; and its objects are to more thoroughly open up thefiber and loosen the dirt and other foreign matter, so that the saidfiber will be more thoroughly cleansed than heretofore, and to sooperate upon the wool that while loosening the dirt the wool will be socombed out as to require less preparation after working than heretofore.WVe accomplish these objects by the mechanism illustrated in theaccompanying drawings, in which Figure 1 is an end elevation, with thecasing removed, of a cone-duster with our improved attachments. Fig. 2is a plan of the same with the top casing and workers removed. Fig. 3shows adetail of a variation in the form and placing of the t'eeth ofthe cone-duster.

A is the frame. B is'the trough through which the wool is fed to themachine. 0 D E are cones provided with teeth 0. e e e are workers placedjust without the path of the teeth 0 c.- a is a screen placed under thecones, through which dirt and dust loosened from the fibers or fromamong them may fall into a dead-air chamber beneath. b is the topcasing, which is not perforated. Zis the passage from one cone toanother through the intervening casing. The cones O D E are driven bybelts running upon pulleys m m m, as shown, placed on their shafts inthe usual and ordinary manner for driving machinery. The pulley m isdriven in any usual and well-known way. Thearrows show the direction ofrotation of the sev eral moving parts. The workers will operate by theaction of the cone-dusters in carrying the fiber past them.

The operation of the device may be thus described: The wool being fed tothe cone 0 through the feed-conduit B, which delivers it near the smallend of the cone-cylinder, by the teeth of which it is taken, is carriedaround in the direction indicated by the arrow, and whatever dirt may beloose in it will drop out through the openings in the bottom casing, a,into the dead-air chamber beneath. As the wool is carried around, thatwhich is most in masses flies out by centrifugal force, so that it iscaught by the teeth of the workers, and by their action, combined withthat of the teeth of the cone, the masses are torn up, and the dirtwhich may be among or adherent to the fibers is loosened, and as thewool fibers are drawn out and pass again around the cylinder the dirtfalls into the dead-air chamber. The wool will by itsrepeated'passagesundertheworkershave all its masses separated, and allthe dirt which can be separated without washing removed, instead of, asis sometimes the case with conedusters having no workers, passing out inmasses,which retain the dirt they carried into the machine. As the taper of the cones is veryconsiderable, the movement of the wool throughthe machine is not prevented by the workers, but only retarded; but suchdelay can be overcome by the use of the fans 9, which create a draft inthe direction which will forward the wool. When the wool has, passed tothe larger end of the cone 0, it is thrown off, and, passing through theopening Z, is taken by the teeth on the smaller end of the next cone, D,and when it reaches the larger end of that cone passes through anopening to the cone E, after traversing which it is discharged throughthe spout f. By such repeated working during the passage of the Wool indifferent directions the cone-duster is made to perform much more workthan an equal cone-surface on a single cone wouldbe capable ofaccomplishing, and by the use of the workers the cone-duster is made todo a considerable amount of the work of straightening out the fibers,and'thus the amount of carding afterward required is greatly diminished.

, What we claim as new and useful is- 1. The combination, with acone-duster cylin der, of one or more toothed worker-rolls and a bonnet,the said rolls having their surfaces substantially parallel to andworking with the conical face of the cylinder and inclosed within saidbonnet, substantially as described.

2. The combination of the cone dust-er C with the cone-duster D, and thefiber-delivery 5 passage Z, leading from the larger end of the former tothe smaller end of the latter, substantially as described.

3. The combination of two cone-clusters in \Vitnesses: one machinehaving their axes placed parallel ARTHUR l3. PLDTPTON,

side the smaller end of the other, with afiberpassage, Z, connectingsaid ends and adapted to conduct the fiber from the one of saidconednsters to the other, substantially as described.
